Turbocharger

If the time has come to replace your Cummins 5.9 turbo, you may be considering a 5.9 Cummins turbo upgrade. If you really want to maximize the amount of boost your turbocharger provides, then it might be worth purchasing a 5.9 Cummins twin turbo kit. This will allow you to ditch your 5.9 Cummins stock turbo and upgrade to a twin-turbo setup. While a stock turbo can boost performance massively, a twin-turbo makes an even bigger difference — often providing up to 40% more boost to the engine when compared to a single turbo.

Still, that isn’t your only option when planning a turbo upgrade for 5.9 Cummins. While the performance boost they provide is superb, twin turbos are very expensive. So if your budget is a little tighter, you may want to consider a high-performance single turbo for your 5.9 24v Cummins turbo upgrade.

Parts like the wastegate actuator aren’t talked about as often but play a vital part in the turbocharger’s function. The Cummins turbo actuator acts like a bypass, allowing gas to pass from the turbine inlet to the turbine outlet without hitting the turbine itself. It plays a vital part in controlling the amount of boost that is sent to the engine itself.
